Cast iron flap valve, mainly used for pipelines in water supply and drainage project, sewage treatment project. Its purpose is to overflow or non-return medium, also used as well lids for vertical shaft.in this paper, the author would like to make a brief introduction to the five features of the cast iron flap valve.
Five Features of the Cast Iron Flap Valve:
(1). Forbidding manual operation at single water flow pipelines or water outlet, equip with standard flange, it can connect to all kinds of pipelines.
(2). PM model flap valve is rubber soft water-stop, good effect, resistant to shock.
(3). FPM model flap valve’s proportion is larger than water under water, the open water head is really low(after gravity nullifying, about 0.06m water head).
(4). Installation form mostly is flange structure, easy to install.
(5). Flap valve helps to save electric energy, manpower, water treatment charges and so on.
The above mentioned text is a brief introduction to the five features of the cast iron flap valve. Flap valve is often seen in gate, it’s the essential fitting for gate. Flap valve is widely used in chemical engineering, petroleum, hydro-junction project, it’s the important part in hydraulic structure. In the production of flap valve, rust protection technology is more important.
